Note (1) Measurement condition of outline dimension . Equipment : Vernier Calipers. Push Force : 500g ⋅f (minimum)
Note (1) Temperature and relative humidity range are shown in the figure below.95 % RH Max. (40 °C ≥ Ta)Maximum wet - bulb temperature at 39 OC or less. (Ta > 40 °C ) No condensation
(2) 2ms, half sine wave, one time for ±X, ±Y, ± Z. (3) 5 - 500 Hz, random vibration, 30min for X, Y, Z.(4) At testing Vibration and Shock, the fixture in holding the Module to be tested have to be
hard and rigid enough so that the Module would not be twisted or bent by the fixture.(5) If product is used for extended time excessively or exposed to high temperatures for extended time,
there is a possibility of wide viewing angle film damage which could affect visual characteristics.
The following items are measured under stable conditions. The optical characteristics should be measured in a dark room or equivalent state with the methods shown in Note (5).Measuring equipment : TOPCON SR-3
* Ta = 25 ± 2 °C, VDD=3.3V, fv= 60Hz, fDCLK = 72.33MHz, IL = 20mA
Note 5) After stabilizing and leaving the panel alone at a given temperature for 30 min , the measurement should be executed. Measurement should be executed in a stable, windless,and dark room.30 min after lighting the backlight. This should be measured in the center of screen. LED current : 20 mA Environment condition : Ta = 25 ± 2 °C

(a) When the module is assembled, It should be attached to the system firmly using every mounting holes. Be careful not to twist and bend the modules.
(b) Refrain from strong mechanical shock and / or any force to the module. In addition to damage, this may cause improper operation or damage to the module.
(c) Note that polarizers are very fragile and could be easily damaged. Do not press or scratchthe surface harder than a HB pencil lead.
(d) Wipe off water droplets or oil immediately. If you leave the droplets for a long time,Staining and discoloration may occur.
(e) If the surface of the polarizer is dirty, clean it using some absorbent cotton or soft cloth.
(f) The desirable cleaners are water, IPA (Isoprophyl Alcohol) or Hexane.Do not use Ketone type materials(ex. Acetone), Ethyl alcohol, Toluene, Ethyl acid or Methyl chloride. It might permanent damage to the polarizer due to chemical reaction.
(g) If the liquid crystal material leaks from the panel, it should be kept away from the eyes or mouth . In case of contact with hands, legs or clothes, it must be washed away thoroughlywith soap.
(h) Protect the module from static , it may cause damage to the C-MOS Gate Array IC.
(i) Use fingerstalls with soft gloves in order to keep display clean during the incoming inspection and assembly process.
(j) Do not disassemble the module.
(k) Do not pull or fold the lamp wire.
(l) Do not adjust the variable resistor which is located on the back side.
(m) Protection film for polarizer on the module shall be slowly peeled off just before use sothat the electrostatic charge can be minimized.
(n) Pins of I/F connector shall not be touched directly with bare hands.www.yslcd.com.tw
(a) Do not leave the module in high temperature, and high humidity for a long time.It is highly recommended to store the module with temperature from 0 to 35 °C and relative humidity of less than 70%.
(b) Do not store the TFT-LCD module in direct sunlight.
(c) The module shall be stored in a dark place. It is prohibited to apply sunlight or fluorescentlight during the store.
3. OPERATION
(a) Do not connect,disconnect the module in the “ Power On” condition.
(b) Power supply should always be turned on/off by following item 6.3 “ Power on/off sequence “.
(c) Module has high frequency circuits. Sufficient suppression to the electromagnetic interference shall be done by system manufacturers. Grounding and shielding methodsmay be important to minimize the interference.
(d) The standard limited warranty is only applicable when the module is used for general notebook applications. If used for purposes other than as specified, SEC is not to be held reliable for the defective operations. It is strongly recommended to contact SEC to find out fitness for a particular purpose.
4. OTHERS
(a) Ultra-violet ray filter is necessary for outdoor operation.
(b) Avoid condensation of water. It may result in improper operation or disconnection of electrode.
(c) Do not exceed the absolute maximum rating value. ( the supply voltage variation, input voltage variation, variation in part contents and environmental temperature, so on) Otherwise the module may be damaged.
(d) If the module displays the same pattern continuously for a long period of time,it can bethe situation when the image “sticks” to the screen.
(e) This module has its circuitry PCB’s on the rear side and should be handled carefully in order not to be stressed. www.yslcd.com.tw
